Sallie 13 #18H
Ector County · Sallie Ann (Spraberry-Wolfcamp) field · Horizontal
Sallie 13 #18H (API 42-135-42790) is a horizontal well in Ector County operated by Diamondback E&P LLC, completed October 23, 2014.
The RRC has issued 2 drilling permits (amended once) between 2013 and 2023, permitted to 12,000 ft.
It was permitted by Firebird Energy LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its 2 leases have reported 1.4M barrels of oil and 3.67M mcf of gas since October 2007, last reporting in July 2026. The leases carry 21 wells, so these are lease totals, not this well alone.
